Radxa CM5 on RPi CM4 IO Board - HDMI not detected

bmagsalan · July 3, 2024, 4:11pm

I tried both of these images:
radxa-cm5-rpi-cm4-io-6_1_bookworm_kde_t2.output.img
radxa-cm5-rpi-cm4-io_debian_bullseye_kde_b2.img

I’m able to login via ssh and the bookworm image I can get the USB ports but still no HDMI

@ken can you give some advice?

Only one HDMI port is supported, you can try another

Tried the other port with the same result.

I looked at rsetup and there is nothing there for hdmi drivers.

I also tried looking and rsetup and didn’t see any overlays for the HDMI.

Pls reload the image，and only hdmi0 is support output.

I tried both.

Here is the guide I followed:

Is there an updated one for Radxa CM5?
